1952-59 Ford Pertronix

Can you tell me what model of pertronix I need for my Ford 1954 with are 6 cyl in 12V ? Thank you soo much ! Stef from France

 

For negative ground? See these two examples;




I believe the 1261 works with the original setup. Points style coil and wires and ballast resistor (if equipped).

Be sure to verify the difference between these two kits. I believe the 91261 is for a later style coil. Hopefully someone else will chime in to confirm.

 

Thank you Adriatic Machine . Yes, negative ground ! and for the coil it is 3 ohm or 1,5 ohm ????

 

I’m not sure, I always have to research those types of details. But the 1261 is a direct drop in for the original equipment

 

I suggest you contact them directly. They'll need to know the part number of the distributor you are using. I'd give them a grade of D for customer service response.

 

The specification page on the Pertronix site lists "coil capacity" as 3 for the Ignitor and 0.6 for the Ignitor II.

 

The Ignitor II has an internal processor and can handle higher current and uses a lower ohm coil. The resistance of the coil with the Pertronix is critical for proper operation. If you have a ballast resistor you usually need to byp*** it and run 12 volts directly to the Pertronix module as well. You can use a ballast resistor for the coil on some but not on the module.

 

If you are using the original 54 distributor and 12V negative ground you probably need one for a 56 six cylinder as the 56 was originally 12V negative ground. Number ? the only way I know for to get the real info is talk tp Pertronix - but from France might be an expensive call. Email should work fine.

 

You have to put the rotor or simply put the electronic kit without a rotor ? Do you have a pic of installation ? Thank you !!!

 

Remove the cap and rotor. Remove the points and condenser. Install magnetic sleeve on shaft, install module where the points were located. Reinstall the rotor and the cap. All directions are included in the kit.

 

Ok thank you !!!!

 

On our 56 with 57-up distributor I installed a Pertronix ll 9 years ago. I also bought their coil because at the time the internet was full of coil failures which seemed to not involve their coil.
I called them and spoke to a technician on the use of a stock ballast resistor and he told me that’s it my choice. He said the spark would not be quite as “hot” due to the lower running voltage but high voltage would still be there for starting.
I asked if the lower continuous lower voltage with possibly extend voltage life and he said “it stands to reason it would”; so I kept it in the circuit.
I check my spark plugs once a year and they always clean and have never needed changing. Just my experience.
